| Abstract | This work presents the design and test of a two-stage planetary traction speed reducer. This is a precision reducer that presents low speed and torque fluctuations, low vibration level, and zero backlash. This reducer does not have gears, transmission is made by the friction between smooth surfaces, which enables the reducer to have zero backlash. A traction fluid is used forming a film pad between the surfaces avoiding the metal-to-metal contact. Theoretical studies concerning the principles of movement and torque transmission, the Hertz contact stresses, and the contact fatigue criteria are performed. The Hertz contact stresses combined with the contact fatigue criterion are used to predict the life of the reducer. The reducer’s configuration, working principle, kinematics and force analysis are described. Finally, tests are performed to determine the reducer precision. These tests are based on measurements of angular transmission error, velocity fluctuation, torsional stiffness and backlash. Results of the angular transmission error and backlash permitted to conclude that the reducer could be classified as a precise device. |
